Fiesta Nacional de España

The National Day of Spain (Spanish: Fiesta Nacional de España) is a national holiday held annually today, October 12. It is also traditionally and commonly referred to as the Día de la Hispanidad (Hispanicity, Spanishness Day), commemorating Spanish legacy worldwide, especially in Hispanic America.
And because this year is on a Thursday its likely that most people will be taking a puente (long weekend).
